In regard to security, there are many fronts to address. From the road safety “first-person” through the active and passive safety as its core legs, to the safety of pedestrians and other vehicles to which, for one reason or another, we can affect. These solutions exist and are varied, but everyone is chasing eradicate the victims: the wounded and dead must be zero. That is the goal.
To achieve this purpose, efforts in solution development budget and account for much interest from manufacturers, and in the case of Toyota all is included in the Toyota Safety Sense project. Assuming that cars are becoming safer, it must take a step towards a new dimension of integrated security that encompasses all points of interest. Today we will see one by one…
Pre-collision system security, to minimize the consequences of an impact
The aim of this security system is to minimize the consequences of a collision, and if possible, avoid it altogether. It is based on millimeter radar and a camera lens that simply looks at what lies ahead and, thanks to radar estimates the distance and the relative acceleration between us and the obstacle.
With the collected data the degree of danger is estimated from the position, speed and predicted path for our vehicle, and the speed and position of other vehicles.
Should be “concluded” there is a possibility of a collision, the system will alert the driver with audible and visual signals, and if enough pressure is applied to the brake (or if the driver has not noticed the event), the system kicks in and helps the driver.
If by some chance, the driver was not able to stop, the car will be who does the work, which makes this system a great ally on the road.
Warning of involuntary change lanes, to minimize distraction
The inadvertent lane change is something that happens, and unfortunately, it is becoming more common. Distractions in the car are large, and many drivers also allow them and are not able to do without them. We talked about the Smartphone as the main cause of distraction, followed by the browser, the sound system and less conversation with other passengers.
It is common to see cars that kept an erratic path because the driver manipulates the Smartphone looking for a message, a fact, or (in the worst and most amazing of all cases) are reading. To prevent an oversight of this caliber take us to adjacent lane or onto the shoulder, the alert system inadvertent lane change takes control. As the sensors detect an unexpected change (change lanes without using the turn signal) alerts the driver with an audible alert.
Intelligent Control of headlamps for greater concentration of night
Night driving presents an extra challenge for drivers. Although a priori may seem like a pleasure, and probably is the fact that there is less traffic, less visible in clear weather, much less if the weather is unstable or just rains, increases the visual fatigue and feeling tired behind the wheel. In addition, the risk of glare is present and we should not despise.
When a car or a pedestrian who can dazzle is detected, the system switches between long and short range, and when the road is clear again active “long”.
At night, and road or highway, we use all the time possible lights reaching without disturbing other drivers, and that means we are attentive enough to switch between long and short range when we are in a position to dazzle others. This aspect is a point of care increases fatigue.
To improve these situations there is such a system, automatic lights-reaching. What they do is controlled independently on and off long-range lighting. When a car or a pedestrian who can dazzle is detected, the system switches between long and short range, and when the road is clear again active “long”.
Security System Pre-Pedestrian Collision Detection
One of the bullets road safety technologies that can remove damage and injuries are pedestrians. Today it is possible to detect and protect pedestrians with sensors, lasers and many systems are based on recognition of human silhouettes (or animals) and calculate all the possibilities of collision and possible solutions to minimize damage.
A Millimeter radar and a camera detect the shape of pedestrians or obstacles and send the necessary information to the control unit to avoid collision
Yes, you’re thinking right because this is one of the strengths of research and development to make the reality autonomous cars.
Pedestrians are very sensitive to damage from abuse for several reasons: the first is obvious, which is that a car traveling at a certain speed is deadly when it collides with a person. The second is that physical and ours? “Settings” are quite incompatible, because when the driver brakes hard, the nose of the car low and is more likely to impact fully in the legs and, in fact, in the area near knees, causing serious injury at the time and in the immediate aftermath.
So many R & D efforts in seeking to minimize both impact damage, as the chances of this occurring are made blow.
This pre-collision system with pedestrian detection is based on millimeter radar and a camera to detect pedestrians or obstacles form and send the required information to the switchboard, where decisions are made and the system comes pre-crash in action.
Adaptive Cruise Control Radar, to keep distances
The safety distance is another hot spot of road safety, mainly because it is not respected everything they should. Maintain proper clearance to the vehicle in front is basic to prevent the sooner an anomaly in his behavior and to have time to react.
This system regulates the speed to ensure that we correct safety distance between cars
Many collisions could be avoided if all drivers were aware of how security measures distance by the speed, especially depending on the surface grip.
To provide a point of autonomy to the car, looking around the problem, there are devices like the Adaptive Cruise Control Radar, which in addition to maintaining the speed you indicate, is capable of regulating it to ensure at all times that we stop the distance correct security. This means that, if necessary, slow to adapt our car. We can see from this chart how it works.
As we can see, the speed control to decelerate arrived 40 km / h, when the system is switched off and we should take control. This system is an ideal partner in the monotonous motorway journeys, where the lack of “action” sometimes leads to a more relaxed state, where care can suffer. With this dynamic control we will be sure not to provoke a collision range.
